Alexandrite, the birthstone for June, is beautifully mysterious. It exhibits the unique phenomenon known as Color Change. Under warm light Chatham created rectangular alexandrites are a reddish-purple while under natural white light they turn a beautiful teal green.

Chatham lab grown rectangular alexandrites exhibit excellent color change because they are grown in a controlled environment in their natural crystal habit, shown left. They are not imitations, rather they are REAL alexandrites carefully grown. Top quality natural alexandrites with excellent color change are rare and extremely expensive. Thankfully, Chatham created alexandrites cost a fraction of the price of mined alexandrites.

Pictures not actual size. Alexandrite is denser than diamond, so it weighs more for the same physical size. Because carat is a measurement of weight, not size, it’s important to order colored stones based on physical size rather than carat weight.
